# Python: Find numbers divisible by nineteen or thirteen from a list of numbers using Lambda

## Python Lambda: Exercise-17 with Solution

Write a Python program to find numbers divisible by nineteen or thirteen from a list of numbers using Lambda.

Sample Solution:

Python Code :

``````nums = [19, 65, 57, 39, 152, 639, 121, 44, 90, 190]
print("Orginal list:")
print(nums)
result = list(filter(lambda x: (x % 19 == 0 or x % 13 == 0), nums))
print("\nNumbers of the above list divisible by nineteen or thirteen:")
print(result)
``````

Sample Output:

```Orginal list:
[19, 65, 57, 39, 152, 639, 121, 44, 90, 190]

Numbers of the above list divisible by nineteen or thirteen:
[19, 65, 57, 39, 152, 190]
```

Python: Cache results with decorators

There is a great way to cache functions with decorators in Python. Caching will help save time and precious resources when there is an expensive function at hand.

Implementation is easy, just import lru_cache from functools library and decorate your function using @lru_cache.

```from functools import lru_cache

@lru_cache(maxsize=None)
def fibo(a):
if a <= 1:
return a
else:
return fibo(a-1) + fibo(a-2)

for i in range(20):
print(fibo(i), end="|")

print("\n\n", fibo.cache_info())
```

Output:

```0|1|1|2|3|5|8|13|21|34|55|89|144|233|377|610|987|1597|2584|4181|

CacheInfo(hits=36, misses=20, maxsize=None, currsize=20)```
